Problems solved by technology

Although this invention partially solves the deficiency of nano-copper powder as a lubricating oil additive, it does not solve the requirements of large-scale mechanical equipment or low-precision mechanical equipment for copper powder particles, nor does it solve the problem of copper-oil separation and precipitation
[0011] The products of "Method for preparing nano-copper lubricating oil additive" (application number 200610165009.3) and "submicron copper-based running-in repair agent and its application" (application number 201010225297.3) have an inconvenience in use: from production to inventory to After distribution, and then in the hands of the user, as long as it exceeds 10 days, the copper oil will be seriously separated. When the user adds to the machine, the small bucket must be shaken, and the large bucket must be stirred, otherwise the sediment cannot be used. From the perspective of the user, such a product is a semi-finished product. , is not conducive to operation, and also affects the trust of users in products ( Figure 8 , Figure 9 )

Abstract

The invention provides a preparation method of an energy saving and emission reduction type lubricating oil additive in the technical field of industry and manufacturing industry, which overcomes the precipitation and agglomeration phenomenon of copper powder in the previous similar technology and avoids the application difficulty and potential mechanical damage caused by the agglomeration of the copper powder. The preparation method comprises the following steps: stirring micron copper powder with low apparent density (0.8-1.00 g / cm<3> and the particle size is 0.1-100 microns) with base oil for 20 minutes according to a proportion of 1:2 by using a planetary stirrer, deoiling by using a centrifugal deoiling machine, taking out the micron copper powder, and roasting for later use; adding the base oil into the copper powder according to a proportion of 1:10, and stirring for 20 minutes by using the planetary stirrer to prepare the micron copper powder lubricating oil additive; adding lubricating oil into the micron copper powder lubricating oil additive according to a proportion of 1:20, and stirring for 20 minutes using the planetary stirrer to prepare a finished product of micron copper powder lubricating oil; adding lubricating grease into the micron copper powder according to a proportion of 1:80, and stirring for 30 minutes by using the planetary stirrer to prepare a finished product of micron copper powder lubricating grease. The specific gravity of the used copper powder is close to that of the oil, and thus the copper powder precipitation phenomenon is well solved.

Description

technical field [0001] The present invention is the preparation method of energy-saving and environment-friendly lubricating oil additive in the technical field of industry and manufacturing industry. The preparation method of the present invention overcomes the phenomenon of copper powder precipitation and agglomeration in similar products in the past ( figure 1 , Figure 8 , Figure 9 ), which avoids the difficulty of use caused by the agglomeration and precipitation of copper powder (the precipitation needs to be used after manual shaking and stirring) and the potential mechanical damage (the increase of local frictional resistance caused by metal precipitation). [0002] This kind of additive with low bulk density micron copper powder and the lubricating oil and grease made have the functions of repairing mechanical scratches and wear, saving electric energy, saving fuel, lowering operating temperature, reducing exhaust emissions, reducing mechanical noise and vibration, ...
